Economical Red Dot Laser Module, 650nm, Class 3R, less than 2.5mW, with APC Driver, 2.6~6V Operation Voltage, D7xL21mm, VLM-650-03 LPA, Laser Head, Made in Taiwan

Worked perfectly for what I needed

It does what I need it to do. Tested with 3 AA batteries in series (still designing the pcb for the final project for this) and saw that it shines as I would expect a laser to do. Wasn't a perfect circle dot as others have mentioned, but it's close enough for my needs.

I had to send this back because it is very misleading. It doesn’t work without having to get some other kind of piece to connect it to and it comes to zero instructions.

While it works fine, it does not display a dot it’s a really short line. Functions fine for what I need but not what I was expecting.

I replaced a burned-out laser guide in my chop saw (Porter Cable/Delta 3802L). Fairly easy replacement. This laser is bright and focused. The saw's power supply worked great - very little messing around with wiring was required. The original laser ($105 to replace !!) gave a line, this replacement laser is only a point of light, but it falls exactly where you need it - where you want to cut.

It worked very well. Nice crisp dot and then all of a sudden the entire module came sliding out of its housing while it was mounted. I tried to place it back in but now it’s not centered. It wasn’t exposed to any extreme heat. It’s unfortunate because it’s a really nice laser for the money.

Perfect laser

This laser LED is surprisingly bright, considering the low power consumption. Very pleased.
